Grader blade actuator

ABSTRACT

a grader blade actuator comprises a frame, a pair of pivot arms connected to said frame, a link member pivotally interconnecting the arms, a blade member, and a diagonal fluid cylinder connecting the link member to the blade member. The blade actuator further comprises a pair of fluid lift cylinders which are of a construction sufficient for connecting each pivot arm to a respective end portion of the blade member. 
     One or both of the lift cylinders has two or more spaced apart releasable connectors 48 and 50 or 48&#39; and 50&#39; which are selectively connectable to the respective pivot arm for providing vertical positioning of the blade member.
